Born on the 6 January 1900 at Vernassal in Auvergne (in the middle of France), he was ordained a priest on Holy Saturday 1924, professor of psychology and of philosophy at the Catholic Institute in Paris from 1929 to 1949. He founded a movement for young people : the ‘Cité des Jeunes' (City of joungs), developed an original training pedagogy based on the apostolic and the group built in the image of the ‘city of God' and with local and temporal expression of this.
Impassioned militant, he founded and presided over the movement ‘Propagande pour l'Unité' (Propaganda for oneness), convinced that the Church must lean on the modern means of propaganda (one would say today ‘communication') and on enthusiastic Christians and decided to spread itself and to communicate itself. He founded and directs "l'Homme Nouveau" (The New man), the journal enrolling to this idea of propaganda and of the unity of Christians. He died in an accident on the 10 August 1949.
Father Fillère, spiritual father of Jean Thévenon, was without any doubt at the origin of the passion of Father Thévenon, to ‘announce the word of God'.
